I recently traded my '05 2.0 TDI (140) SE manual for a '08 2.0 TDI (140) S Line s-tronic. The car was serviced and had the belt changed before I picked it up. I'm doing the same daily drive (in the same style) I was doing before but I'm finding the fuel consumption to be brutal. According to the DIS I've averaged mid-40s MPG on each journey since I last filled up yet with the needle on just over half I've only done 200 miles. In my old A3 I'd have done 200 miles on a quarter of a tank. The car is due a gearbox service but I can't think of anything that could be causing such poor fuel consumption. As far as I know it's not modded. Just wondered whether other owners of similar cars are getting similar figures? My daily commute is a mix of town traffic and a 8-10 mile dual carriage way stretch. Also, is there a way to stop the DIS resetting the average fuel consumption back to zero randomly? The car's manual doesn't cover the DIS.
